LABEL DESCRIPTION
STP Active Select this check box to activate STP on this port.
Priority Priority is used in determining the root device, root port and designated port.
The device with the highest priority (lowest numeric value) becomes the
STP root device. If all devices have the same priority, the device with the
lowest MAC address will then become the root device. The allowed range is
0 to 255. The lower the numeric value you assign, the higher the priority for
this device.
Path Cost Path cost is the cost of transmitting a frame on to a LAN through that port. It
is assigned according to the speed of the link. The slower the media, the
higher the cost (refer to the table on path cost in the section on STP).
